Superb Quality Wireless Transmission

The digital wireless microphone system transmits high- quality 24-bit/48 kHz sampling digital audio signals in a specific frequency bandwidth that meets the wireless-communication regulations of each country. Utilising an original Sony codec, based on Sony’s many years of experience in engineering audio products,the system delivers a wide dynamic range of more than 106 dB, a wide frequency response of 20 Hz to 20 kHz and an excellent system latency of 3.6 ms.

Simultaneous Multi-channel Operation

The digital wireless microphone system allows for large- scale multi-channel operations. Thanks to the newly developed digital modulator, the system realises an intermodulation-free,equally spaced channel allocation. The digital wireless transmission technology used in this system enables a significant increase in the number of simultaneous digital wireless systems in comparison with current analogue wireless systems. For example, up to 16 channels of simultaneous operation is possible in an 8 MHz bandwidth TV channel in Europe.

This system also provides the option of using existing WL-800 Series channel plans. In this configuration, the digital wireless system reliably operates alongside the WL-800 Series analogue wireless systems, without concern for having analogue and digital wireless systems interfering with each other.

Stable and Secure Transmission

Incorporating a newly-developed digital modulator, the digital wireless microphone system allows highly stable and secure wireless transmission that is extremely tolerant to RF interference. The system transmits digitally modulated and encrypted data to minimise the risk of interception, providing highly secure transmission. For secure and confidential commu- nication, the system provides two communication modes: peer-to-peer mode and password mode. In peer-to-peer mode, wireless communication between a DWT-B01 transmitter and DWR-S01D receiver can be established by exchanging an encryption key that is generated by the transmitter. In password mode, multiple transmitters and receivers can be configured by setting all devices with the same user-designated password. In addition, this mode supports broadcast communication, which enables multiple receivers to receive audio signals from one transmitter.

Pre-programmed Frequency Groups

To make it easy to choose the correct frequencies for simultaneous multi-channel operation, the optimum intermodulation-free frequencies are stored on each DWR-S01D receiver. These frequencies – all of which have been calculated and tested – are arranged in groups, with each group pre-programmed to allow interference-free operation. The digital wireless microphone system operates within the following frequency ranges:

Frequency range

CE67

838 to 862 MHz (TV 67 to 69 channels)

 

*The DWR-S01D receiver supports a 24 MHz band RF carrier frequency range. When using the DWR-S01D receiver in either the 798 to 822 MHz (TV 62 to 64 channels) or 838 to 862 MHz (TV 67 to 69 channels) frequency range, please contact your nearest Sony office or authorised dealer.

Metadata Transmission

In addition to audio signals, a variety of information about the DWT-B01 transmitter – such as audio input peak level, remaining battery capacity, low-cut filter frequency and attenuator level – can be wirelessly transmitted to the DWR-S01 receiver as metadata. This allows users to monitor the status of the transmitter from the DWR-S01D receiver, offering high operational convenience.
